single band vs. dual band pulsed light technology for the treatment of photodamage - a split face comparison study

Conditions: Photodamage

Summary: both the dye - vl 500 - 600 nm and the dual band will improve significantly the appearance of photo damage with high efficacy including; safety, minimal discomfort and downtime.
